HARNESS FOR WEAVING SEAMLESS BAGS.

Speccation of Letters Patent No. 15,415, dated July 29, 1856.

To all whom it may concern:

Be it known that I, ALGERNON L. COLE, of Windham, in the county of Cumberland, in the State of Maine, have invented a new and useful Improvement in the Art of Manufacturing Seamless Bags; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and to the letters of reference thereon.

The nature of my invention consists in providing each leaf of harness with an additional row of eyes to the one row now in use; thereby dispensing with the use of an additional set of cams. To spring two distinct warps, I use one set of cams, four leaves of harness being required to weave a twilled or miXed twilled bag, and'only two leaves being required to weave a plain bag. And with this kind of harness, I weave two distinct warps into plain or twilled cloth in the same loom, one warp being above the other, and two sets of shuttle-boxes, one being placed above the other and stationary.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my loom in any of the known forms, and apply thereto any of the known motions for raising and falling the shuttleboxes. But to obviate the necessity of using two sets of cams to spring two warps when drawn through. a harness, with one row of eyes only, I construct a harness with two rows of eyes upon each leaf, as shown at K K, Figures l and 2, in the accompanying drawing; which is a perspective view of the harness in a position for weaving the open fabric or bag, the harness being made in two parts, as sho-wn at A A and B B with the eyes drawn apart so as to bring heddle eyes K, Fig. 1, in like position with heddle eyes K, Fig. 2, the shafts being fastened to end pieces C C by tenon or otherwise, the

parts being united by means of screws or otherwise cl d Z Z through slots in the sliding half of end pieces C C fo-r the purpose of admitting A A to be brought down on a level with B B, and the warp being drawn through the harness, and the harness hung in the loom in the usual form.

With the spring of the harness I throw the filling irstthrough the lower warp; then by the rising of the shuttle-boxes, the harness remaining at rest, I throw it through the upper warp to the box from which it started; then by the falling of the shuttleboXes, and at the next spring of the harness, I throw the filling through the lower warp again; and so continue until the cylinder or open part of the bag is wove. I then proceed to weave the bottom by depressing levers E E at their junction F, which throws out the pivots on springs Gr G, attached to the sliding half of the end pieces C C, which brings A A on a level with B B and brings both warps into one. I then stop the rising of the shuttle-boxes, and give a continued motion to the harness. Then I throw the filling through the warp, with the spring of the harness, in the same manner as when weaving plain cloth, which weaves the bottom or closed part of the fabric. I then open the harness, as shown at Fig. 1, put on the vibrating motion to the shuttle-boxes rand rest motion to the harness cams, and

harness as herein described, or any other` substantially the same.
